We deene a new Markov chain on (proper) k-colourings of graphs, and relate its convergence properties to the maximum degree of the graph. The chain is shown to have bounds on convergence time appreciably better than those for the well-known Jerrum/Salas{Sokal chain in most circumstances. For the case k = 22, we provide a dramatic decrease in running time. We also show improvements whenever the ...

I would like to thank the comments by the seminar participants at Autonomous University of Barcelona, III BBV Financial Economics Conference (Bilbao) and X Conference ACEDE 2000 (Oviedo), for their useful comments. The ECASS at University of Essex (UK) and PB97-0185-C03-01 sponsored this study with their resources. This study has been supervised by Doctor Antoni Serra Ramoneda and Doctor Vicent...

Vargas, López, Salas, and Thinus-Blanc showed that goldfish (Carassius auratus) can use both geometric and featural cues in relocating a target corner in a rectangular enclosure. When featural cues (arrangement of striped walls) were put in conflict with geometric cues, results differed according to target location during training. Vargas, López, et al. explained the results of their cue confli...

Resumen. Se analizan algunos aspectos relacionados con el diseño de bibliotecas digitales que ofrecen una interfaz de usuario basada en técnicas de realidad virtual, con las que se pueden crear edificios tridimensionales en los que se depositan libros virtuales a los que un lector puede acceder recorriendo, mediante un procedimiento de “inmersión”, las diferentes salas y pasillos de la bibliote...

One current response to group work is that in publications addressed to management, work designers, and corporate consultants, the main interest seems to lie in process-related support of cooperation (e.g., training and moderating of group processes), in order to enable or select cooperation-oriented workers (e.g., Salas, Cooke, & Rosen, 2008; Tannenbaum, Salas, & Cannon-Bowers, 1996). It is ar...

We define a new Markov chain on (proper) k-colourings of graphs, and relate its convergence properties to the maximum degree ∆ of the graph. The chain is shown to have bounds on convergence time appreciably better than those for the wellknown Jerrum/Salas–Sokal chain in most circumstances. For the case k = 2∆, we provide a dramatic decrease in running time. We also show improvements whenever th...
